Abstract: Automatic equipments workshop in the production process, the statistics and reports for various data is the condition that the statistics after the production. From the system perspective, this is an off-line control system, and the time difference will increase the failure rate and reduce the efficiency of the equipment manufacturing products. According to this problem, the intelligent network management scheme for the production equipment is designed in the paper, as aluminum electrolytic capacitor production equipment an example, the network control system (NCS) is introduced into the equipment management of production of aluminum electrolytic capacitors, and the design idea and structure are given. Through the design, the intelligent management of aluminum electrolytic capacitor production equipment is realized, which can ensure the efficient, real-time and accuracy of each production link in capacitor.

Abstract: The increase of capacitance on dielectric layer is associated with enlargement of etched surface area of electrodes for aluminum electrolytic capacitors. Etched tunnels extending along [100] directions are formed by crystallographic dissolution of aluminum in a chloride solution. This study has been focused primarily on the effects of addition of inhibitors to hydrochloric acid solution on the increase of the surface area by Electrochemical Impedance Spectroscopy (EIS). The addition of 3 % ethylene glycol was more effective for the enlargement of the surface area comparing with those of 1M sulfuric acid and no additive. And it was observed by TEM that the tunnels were grown straight and parallel to [100] directions.
